PROBLEM TO BE SOLVED: To provide a heliport foldable handrail capable of being easily and quickly laid down and erected by one person.SOLUTION: A heliport foldable handrail 13 has a pair of braces 17 and a cap piece 18 that is disposed across the braces. The brace comprises: a flat plate-like fixed brace 19, which is fixed to a steel stringer 23; and a flat plate-like foldable brace 20, which is connected to the fixed brace so as to be freely laid down and erected. A vertical long hole part, a vertical groove part with one open end and a folding guide piece 30 that continues from the vertical groove part and expands are formed at an upper part of the fixed brace. A first small hole, which is tightened to the long hole part with a bolt-nut 33 so as to freely vertically move, and a second small hole, which is engageably and disengageably tightened to the vertical groove part with a bolt-nut 34, are formed at a lower part of the foldable brace.SELECTED DRAWING: Figure 3
